The present disclosure generally pertains to systems and methods for communicating data. The lenticular units consist of lenticular plates that are capable of visualizing various clinically relevant examination objects. Then, when a transition edge of a sensing signal applied on the DLL occurs at a start of a second period of the external clock signal, the external clock signal is inhibited to pass through the delay cells and the number of the delay cells through which the external signal pass during the first period of the external clock signal is counted. The unit can also optionally contain removable or fixed earmuffs, a removable or fixed electronics module that can contain a radio, MPEG player or other electronics, removable or fixed earphone andor a removable or fixed microphone. Together with data size of lossless compression data, such as RAW data, not becoming large, the processing to do this is carried out in a short time.
